Thread: a fix for my Intermittent USB printer

after upgrading 10.04 (maybe 10.10) printing hp laserjet 6l became intermittent. on rare occations worked. connected via belkin usb parallel lead. computer running 11.10.

after 18 months of trying , that, following fixed me:
lsusb
displays: bus 002 device 004: id 050d:0002 belkin components
sudo chmod a+w /dev/bus/usb/002/004
, fixed! @ least right is.

apparently if make "lp" group, , add write access group:
there no need chmod again.

...someone elses example:
~$ ls -l /dev/bus/usb/004
total 0
crw-rw-r-- 1 root root 189, 640 2010-10-11 23:09 001
crw-rw-r-- 1 root root 189, 641 2010-10-11 23:09 002
crw-rw-r--+ 1 root lp 189, 642 2010-10-12 00:14 003

sprog,

many - has helped me enormously. think solution intermittant printing problem have in 12.10.

however, magic lasts until next reboot. after has rebooted intermittant problem returns.

can see list of items on usb hub, similar listed in last post, this:

code:

ogp@desktop:/dev/bus/usb/004$ ls -l  total 0  crw-rw-r--  1 root root 189, 384 feb 12 14:29 001  crw-rw-r--+ 1 root root 189, 385 feb 12 14:29 002  crw-rw-rw-  1 root lp   189, 386 feb 12 18:54 003

what mean "apparently if make "lp" group, , add write access group:
there no need chmod again." permanent solution problem?

again.
